My invention relates to stenciling, and includes among its objects and advantages a hand stencil stamp embodying certain features which I have found particularly advantageous in such devices.

5 In the accompanying drawing:

Figure 1 is an end elevation of a device according to the invention;

Figure 2 is a side elevation partly in section;

Figure 3 is a top plan view partly in section;

l Figure 4 is an enlarged sectional View taken along the line 4-4 of Figure 3; and

Figure 5 is a plan view of a backing sheet associated with the stencil sheet.

In the embodiment of the invention selected for l5 illustration, I0 designates a hollow body provided with a handle I2 mounted upon a strap 14 having its ends fastened to the body I0 by rivets I6. The top of the body is closed by means of a cover comprising portions I8 and 25 recessed at 22 for receiving the strap I4. The cover protects the fingers of the user from becoming soiled by the stenciling ink in the body Ill. Each cover portion is provided with a depending flange 24 slightly narrower than the portions themselves to permit 25 the flanges to" be positioned within the body l0 and in abutment with the vertical side walls 26 of the body, as indicated in Figure 3 where the upper ends of the anges 24 abut the side wall portion 3l, and the lower ends abut the side wall 30 portion'33. 4 When the cover is closed, the flanges Y 24 abut each other as illustratedin Figure 1. At this time the cover portions I8 and 20 are firmly associated with the body 1D, since the strap I4 prevents lateral or endwise movement of the portions. The flanges 24, in addition to preventing lateral movement of the inner ends of the cover portions I8 and 20, function as pivots for the cover portions when their outer ends are lifted upwardly as indicated in dotted lines in Figure 2. The length of the flanges is such that the walls ze .will be spread apart slightly when the flangesare pressed therebetween. Thus the flanges will be effectively held `in frictional assembly with the body l0 by the pressure of the sides 26 upon the ends of the anges. I have provided a grip member 23 upon each of the cover portions. Y g The body I6 has a framework of vertical peripheral walls, indicated as a whole by the reference character 26. The entire framework comprises the inner peripheral frame 30 and the outer `peripheral frame 32, The frame 32is larger than the frame 30 and the narrow peripheral groove between them receives and holds the up-turned edges of the metallic bottom 36.

Each frame 30 and 32 is made up of two dupli- (Cl. lolcate U shaped elements. The element 3| of frame 33 begins at the lower right hand corner of Figure 3 and extends across the end and along the other side to the upper left hand corner. The element 33 completes the inner frame 3D, extend- 5 ing from the upper left hand corner of Figure 3 across the left end and along the lower side to the lower right hand corner. It will be seen that rotation of element 3l one hundred eighty degrees about the center of Figure 3 will bring it 10 within the position of element 33.

The frame 32 is made up in the same way of elements 35 and 31 except that the diagonally opposite abutment Vjoints are at the vcorners of the frame remote from the joints of the frame 30, l5 as clearly shown in the upper right hand 4corner of Figure 3.

Each of the elements 3l, 33, 35, and 31 comprises a short leg and a long leg and a crosspiece or bight connecting the legs into a YU-shaped 20 structure. The bights of the elements 3| and 31 together make up the right end of the completed frame, as viewed in Figure 3, and the bights of elements 33 and 35 similarly make up the left end of the frame. All four bights have arcuate lower 25 edges indicated at 38 in Figures 1 and 4, conforming to the curvature of the bottom 36.

Along the sides of the bottom 36 the edges are turned up as at 34 in Figure 4, and entered between the frames 30 and'32. Along the ends'the 30 edge is slotted before turning up into tongues 39 to reduce the die work needed to shape the metal'. These fingers enter between the lower edges of the inner end walls 40 constituting the bights of the frame elements 3| and 33, and the outer end walls 35 42 constituting the bights of the frame elements `;35 and 31. After the bottom is assembled with the frame work, the whole may be spotwelded together.

An inking pad or stencil backing 46 is placed 40 adjacent the curved foraminous bottom 36. The sides of the inking pad are clamped to the sides 26 of the body I6 by means of metal straps 4B. Screws 5D having annular grooves 52 in their heads clamp one of the straps to the body, while 45 the other strap is clamped thereto by ordinary screws 54. The screws 50 Vserve an additional function as attaching means for one end of a 'stencil sheet 56. One edge of the stencil sheet is glued to a paper backing sheet 58 as indicated 50 at 59.

In Figure 5, I have shown the glued together portions of the stencil sheet and the backing sheet as being provided with a plurality of'openings 60. These openings are spaced apart dis- 55 tances equal to the spacing of the screws 50, so that one edge of the stencil may be easily and quickly associated with the body I0 by merely passing the screws 50 through the openings 60. The grooves 52 receive the edges of the material defining the openings 6B, so that this edge of the stencil sheet is effectively connected with the screws when it is stretched across the inking pad 46.

The backing sheet 58 may be temporarily associated with the stencil sheet or permanently associated therewith depending upon the nature of the work being done. In Figure 5, I have indicated a line of perforations 62 in the backing sheet 58 which permits the sheet to be detached from the remaining portion glue-d to the stencil sheet 56. The opposite edge of the backing remains free, while the opposite edge of the stencil is fastened to the opposite wall 26 by means of a tension bar 64. This bar is provided with two wide portions 66 having slots .68 for receiving screws 1D. Nuts 'I2 upon the screw 'l0 are arranged for clamping the tension bar against its side 26 of the bottom I8.

Referring to Figures 2 and 4, it will be noted that the lower edge of the bar 64 is bent around a small Wire I4 for providing a lateral projection arranged to press against the edge of the stencil sheet 56 and clamp the latter against the inking pad 46. The inner ends of the screws 'I8 are X- edly connected with the wall 26, so that the screws will remain fixed even though the nuts 'l2 are loosened for releasing the tension bar 64.

It will be noted that the tension bar 64 is associated with the screws 'l0 by a sliding movement in contact with the stencil sheet 56 in a direction tending to stretch the sheet. With the sheet 56 as taut as it can conveniently be held by hand, the bar is placed in a slightly lower position than that shown in Figure fi, and then slid up to the position of Figure 4. This movement of the bar is guided by engagement of the screws 10 in slots 68. As soon as the movement is completed, a tightening of the nuts 'l2 clamps the whole in assembled position ready for use.

I have shown longitudinal lines 16 and 'i8 and transverse lines and 82 printed upon that face of the backing sheet 58 adjacent the stencil sheet 56. These lines indicate the top, bottom, and side limits within which reading matter should be cut in the stencil. I have also shown longitudinal lines 84 and 86 representing areas within which printing matter should be conned when stenciling postcards. These lines, in addition to defining the limitsV of the stencil sheet 56, also serve as marks to guide the user in positioning sheets to be stenciled.

The foraminous bottom is constructed from material having suflicient rigidity to resist distortion when the device is placed under stenciling pressure, while the inking pad 38 is of sufficient thickness and flexibility to provide compensation for irregularities of surface met with in stenciling. I provide an outer facing 88 of iine linen cloth adjacent the outer face of the inking pad which prevents any of the bers of the inking pad from being worked into the stencil sheet 56.

Without further elaborationthe foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
